Glibc by default creates crti/crtn by compiling one C file, and then spliting the output into two assembly language files. This works on systems with dumb assemblers. It does not work on IA-64. This was changed in August 2000. crti/crtn are now generated from IA-64 assembly. >Correction. Redhat 7.0.98 (Wolverine) also has a buggy version of >crtn.o. You will have to elaborate. My copy here has no unwind info, and hence the unwind info can't possibly be missing relocations. If your complaint is that there is no unwind info, then it needs to be added to the assembly code in glibc. See libc/sysdeps/ia64/elf/initfini.c. Jim
